WEATHER-STRIP.

Specification of Letters Patent.

Patented Dec. 24,1912.

Application filed January 23, 1912. Serial No. 672,851.

To all whom 2'25 may concern Be it known that I, Gnonen L. GODFREY, acitizen of the United States, and a resident of the city of New York,borough of Manhattan, in the county and State of New York, have inventeda new and Improved Weather-Strip, of which the following is a full,clear, and exact description.

Among the principal objects which the present invention has in view are:to pro: vide a metallic strip of the character mentioned, adapted toclose an aperture irregular in form and varying in width; to provide astrip of the character mentioned hav ing a rigid metal casing, a movablestop member mounted therein, and means carried in said casing forcompelling the sections of said stop member to conform with the contourof the opening to which the strip is applied; and to provide a simple,efficient and economical construction for a strip of the charactermentioned.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is a frontelevation of a fragment of a window and frame therefor, showing inconnection therewith a weather strip constructed and arranged inaccordance with the present invention; Fig. 2 is a vertical crosssection, on an enlarged scale, taken on the line 22 in Fig. 3; Fig. 3 isa vertical longitudinal section taken on the line 3-3 in Fig. 2; Fig. 4is a top edge view of the movable member employed in the presentconstruction; and Fig. 5 is a top View of a spring guide strip adaptedfor use in connec tion with the present invention.

As seen in the accompanying drawings, the construction consistsprimarily in a fixed part or casing 10, a movable part or strip 11, anda plurality or battery of springs 12. A guide strip 13 is the fourthelement of the construction. When these parts are assembledsubstantially as shown in Figs. 2 and 8, they constitute an article ofcommerce which may be sold by bulk or specified length. for applicationto window and door openings, in a manner well known in the art.

The casing is constructed from sheet metal bent upon itself near themedian line thereof to form, in double thickness, a fastening strip 14:.The strip 14 is perforated at suitable intervals to receive screws 15 orother fastening devices. The sheet of metal forming the casing 10 isfurther shaped to provide a box-like channel, the lower or opening edgeswhereof are inturned to form lengthwise grooves 16, 1G, in which areseated overturned flanges 17, 1.7 of the flared sides of the strip 11.

The strip 11 is formed from a suitable sheet metal, preferably a thinspring metal. The length of metal from which the strip 11 is constructedis severed by cuts 18, 18 and 19, 19, which cuts are extended from nearthe median line of the said length of metal to the lateral edgesthereof. The cuts 18 and 19, as best seen in Fig. 4 of drawings, aredisposed in staggered relation. The staggered relation of the cuts 18and 19 is provided to partially avoid the seepage or passage of airthrough the window opening, to guard which this strip is provided.

At the median line of the length of metal above referred to, and betweenthe inner ends of the cuts 18 and 19, the metal is bent about a springwire 20. The diameter of the wire 20 is such that the inner ends of thecuts 18 and 19 juxtapose the bent portion of the strip covering the saidwire. The construction, therefore, presents a strip which may bevertically deflected to meet the requirements of the same, to fit thewindow frame or door opening.

To compel the strip 11 to hug the frame of the window or door opening, Iprovide the springs 12. The number of springs 12 employed will dependupon the character of the work required of the strip 11. I prefer theconstruction such as shown in Fig. 3, wherein a spring 12 is employedfor each of'the severed sections comprised between the cuts 18, 18.

To maintain the springs 12 in spaced relation. I have provided the guidestrip 13. The strip 13 is formed substantially as seen in Figs. 3 and 5,having a body portion which rests at the top of the channel of thecasing 10, from which body portion is depended centrally a number oftongues 21. The width of the tongues 21 is approximatcly the diameter ofthe springs 12. The tongues 21 extend between the flared sides of thestrip 11, and permit the rise and fall of the said strip in its serviceoperation.

It is obvious that the parts constituting the invention are readily andquickly assembled, it being only necessary, after the casing 10, thestrip 11 and the guide strip 13 are shaped, to thread the said strips 11and 13 into the channel of the casing 10. WVhile assembling the strips13 and 11-, it is necessary to thread over each of the tongues 21, aspring 12.

In commerce, it is designed that the weather strip above described andshown in the accompanying drawings, shall be delivered to the trade instock lengths, which may be sawed or otherwise cut to length as theparticular installation demands.

To more securely close the oint bet-ween the frame and the door or sash,the felt or other soft strip 22 is secured around the strip edgecontaining the wire 20. To hold the strip 22, a metal strip 23, havingedges 24 is overturned upon the raw edges of the said felt strip. Thestrip, 23, may be slipped over the round or bearing edge of the strip11, and where two or more pieces of the weather strip are used the feltshod strip 23, may bridge the butted ends of the strip 11.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. A weather strip, having an inverted metal channelmember, shaped to form an upwardly-extended fastening strip, and havinginteriorly-extended upwardly-turned holding flanges; a movable striphaving a flexible median portion, and a plurality of partially severedsections extended between each lateral edge of said strip and saidmedian portion, said edges having overturned downwardly-extended flangesto engage the upturned flanges of said channel member; and a pluralityof spiral springs disposed downwardly-extended flanges to engage theupturned flanges of said channel member, a plurality of spiral springsdisposed in said channel member to normally extend the differentsections of said movable member from said channel member; and a guidestrip to rest within said channel member, and having a plurality oftongues extended therefrom to rest within said springs, to maintain thespacing thereof.

3. A weather-strip, having an inverted metal. channel member severedalternately on both sides from the lateral edges to near the medianlongitudinal center a wire rigidly held in said member by bending saidmember around said wire; and means attachable to a fixed structure toguide said channel member.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
